Tech Inspection

Tech inspection requirements are all based on keeping you and others safe out on the track and minimizing event down time. It is the drivers responsibility to ensure the car is safe to operate and all safety gear is in good condition and installed properly.

You will be given the chance to correct any unsafe items and be re-inspected. If you are unable to correct the issue and cannot pass tech you will receive a refund of your driving fee.

If you do not pass tech and miss your runs we cannot make any special accommodations. Come locked and loaded ready to rock.

Oil Leaks

Many cars have been leaking fluids at every event. This is not only unsafe, it causes extra work for the volunteers as we have to clean it up at the end of the day.

Check your engine, transmission, differential, power steering, and cooling system. If there is ANY oily dirt buildup you have a fluid leak. Also check all fluid levels and ensure they are not overfilled which will cause overflow out the breather. Fix any leaks before you attend another event. Simple!

It is strongly recommended that all drivers install catch cans on their transmissions and differentials to catch any overflowing fluid. Catch cans are available for a reasonable price and can be home made out of cheep stuff like empty metal cans.

If you car is found leaking fluids on the track you will not be allowed to run until it is fixed and you will not be given any re-runs.

Minimum Tech Inspection Requirements 3/8ths Course:

Driver Safety Gear

  1. All helmets for driver or passenger must be at a minimum DOT rated open or full face style in good condition. Helmets must cover the temples and ears. 'Skull Cap' style motorcycle style helmets are not allowed.
  2. Snell SA, K, or M 95 or newer rated helmets are strongly recommended.
  3. If you bring a helmet to tech inspection that does not meet the safety requirements the chief of tech must hold your helmet for the duration of the event to prevent it from being used.
  4. Vehicle occupants must wear full length pants and short sleeved shirt at minimum while on course. Closed toed shoes required. Nylon apparel is prohibited in cars on track.

Ride Along Passenger Equipment Requirements

  1. If any of the occupant safety equipment does conform to the the rules on the passenger side the vehicle is not allowed to take ride along passengers. Tech officials are required to place an "X" mark on the passenger side of the windshield that must remain in place for the duration of the event to alert course workers that passengers are not allowed. Modifying or tampering with the mark to circumvent passenger restriction is punishable by ejection from the event and immediate escort off the property without refund.

Hardware

  1. All non OEM hardware used in the mounting of seats, seat belts, batteries, fire extinguishers, bolt in roll cages, parts weighing more than 5 lbs., or other structural components must be SAE Grade 5 or better with a 5/16" (8mm) minimum diameter.
  2. Any hardware attached through thin sheet metal for parts weighing more than 5lbs must use a backing washer or plate with a minimum outside diameter of one inch (1") or greater.

Fuel System

  1. Metal Fuel Filters are required (no plastic or glass – fire hazard).
  2. Fuel lines or fuel system components may never be located in the drivers compartment regardless of plumbing construction.
  3. Fuel Tanks and fuel system components must be completely separated from the drivers compartment by a permanently mounted .036” steel or .059” aluminum bulkhead firewall enclosure that is sealed "light tight".

Electrical System / Batteries

  1. Terminal Insulation - The positive battery terminal MUST BE securely covered and insulated with an OEM style plastic or rubber cover. Any additional terminals on the constant hot positive battery and starter cables must also have non conductive insulating covers.
  2. Mounting - Batteries must be securely fastened with metal OEM style or better mounting hardware to the vehicle unibody/frame.
  3. Mounting of Batteries Located in the Driver Compartment - Batteries mounted in the driver compartment must use heavy duty hardware to prevent the battery from breaking free in a collision. Hardware must be SAE Grade 5 or better with a 5/16" (8mm) minimum diameter nut and bolts. The minimum allowed thickness for aftermarket or fabricated mounting brackets is 1/8" (3.1mm). Large surface area (1" diameter minimum) backing washers must be used when mounting bolts through sheet metal
  4. Fusible Link Requirements - Batteries moved from the manufacturer’s original location must have a fuse or circuit breaker rated at 75 amps or higher installed inline on the positive battery cable. The fusible link must be mounted within 12" (30cm) of the battery terminal measured along the length of the cable. The fusible link must completely isolate the battery from all electrical circuits in order to protect from shorts during collisions and battery cable damage.
  5. Containers for Unsealed Batteries - Any non-sealed wet-cell type battery relocated from the manufacturer’s original location must be in a non-conductive marine-type container to protect vehicle occupants from battery fluid spills. The container must completely enclose the battery and the lid must securely latch. All the above battery mounting rules still apply. The battery must be securely fastened to the chassis or frame independent of and inside of the battery container. The positive terminal(s) must be insulated, and required fuse installed on the positive cable. Sealed gel cell or dry cell (AGM, Li-ion) type batteries are exempt from the container requirement.

Cooling System

  1. A Radiator catch can must be in place to collect coolant overflow. Aftermarket containers shall have a minimum capacity of 1 US Pint or 0.5 Liter.
  2. Antifreeze coolant is allowed to be used. We do recommend not using antifreeze to avoid the ire of your fellow drivers should you have a leak on course.

Drivetrain

  1. Throttle return action shall be safe and positive.
  2. No fuel, oil, water or brake fluid leaks should be observed when the engine is running or at any time during the event. If you have any oil build up around drivetrain components clean and fix the source of the leak before the event.

Exhaust System / Noise

  1. Mufflers strongly recommend. Sound limit is 92db at 75 feet at any point on the track. There will be no grace period. Cars over 92db will not be allowed to run until noise level is fixed. Sound may be measured at any time during an event.

Wheels, Tires, and Suspension

  1. All wheel lugs present with lug nuts. Nuts must have at least 6 full turns of engagement (You may be required to remove wheel spacers).
  2. Tire pressure must be above the manufacturer's recommended minimum.
  3. Wheel bearings, shocks, steering, and suspension shall be in good operating condition with no play.
  4. Tires must be in good condition, with no cords or belts showing and no cracks in the tread or sidewall.
  5. No damaged wheels that pose a hazard of the tire suddenly losing pressure (major lip bends, cracks, etc).

Exterior

  1. Windshields must not have any damage impairing vision or cracks covering more than 50% of the windshield in any direction.
  2. Body panels such as bumpers and side skirts must be solidly attached or removed. If a body panel comes lose during a run it must either be re-attached or removed before taking another run. You will be required to remove the panel if it falls off more than 2 times.

Interior

  1. Throttle, brake, and clutch pedals checked for proper operation. Throttle pedal must return to ‘closed’ position properly and brakes must operate safely.
  2. Wood rim steering wheels are prohibited.
  3. Seats must be solidly mounted at 4 points with OEM or conforming size hardware and mounts for aftermarket and modified seat components. Seat(s) must have a headrest suitable for preventing whiplash.
  4. Seat belts must be fully mounted with bolts present at all attachment points and free of any visible cuts or fraying.
  5. Aftermarket harness are recommended to be DOT, SFI, or FIA certified. The minimum requirement for aftermarket belts is a 3 point harness with 2" or greater strap width. Belts must be installed according to the manufacturers instructions. Lap belt must fit snugly over the pelvic bones and shoulder when seated and strapped in. The angle of the shoulder belts shall not exceed 45* angle below horizontal or 10* above horizontal. Seat backs must have a port hole to retain the harness belts and prevent it from sliding off the shoulders in an impact and the shoulder belts must be routed through it. Harness attachment points that do not use OEM hardware or seat belt mounting bosses must use hardware that conforms to the minimum hardware specifications and use a minimum of two square inch (2 sq. in.) backing plates when mounting to sheet metal. See the Schroth installation guide if you have an aftermarket harness for detailed installation guidelines.
  6. Floor mats must be removed from drivers side
  7. All loose objects larger than one square inch (1" sq) in any dimension must removed from the vehicle. Small lightweight items such as cell phones may be stored in latching storage compartments. Open top compartments such as cup holders are not allowed storage areas. The intent is to prevent loose objects from getting lodged under the pedals or turning into flying hazards during collisions.
  8. Any items such as electronic devices must be securely attached. Subwoofers and amplifiers that are not mounted with hardware suitable for the weight of the component must be removed from the vehicle to pass tech.
  9. Any camera mount affixed either internally or externally must have a secondary strap of suitable strength that will restrain the device and prevent it from contacting the driver or falling on the track in the event that the camera mount fails.
  10. Cameras may not be hand held while the car is on course. If a hand held camera is observed in use on the track the Grid official must take possession of the camera and hold it for the remaining duration of the run group. Multiple violations of this rule will result in loss of ride along privileges for the remainder of the event.

Convertibles

  1. Convertibles must have a minimum of a 4 point roll bar that conforms to or exceeds SOLO Rules Appendix C (pages 242 - 244). The roll bar must be higher than the drivers helmet when normally seated and the main hoop not more than 6" behind the driver.

Roll Cage and 3/8ths Tandem Requirements

  1. A conforming roll cage is required to participate in tandem runs.
  2. Forward braces and portions of the main hoop subject to contact by the occupant’s helmet (as seated normally and restrained by seatbelt/shoulder harness) should be padded. At minimum the horizontal bar running parallel across the top of the window from the main hoop to the A pillar must be padded to pass tech. Depending on seating position this could include the occupant facing side of the main hoop located above above the horizontal plane of the harness bar and tubing within three feet (3') of the occupant's helmet. Padding must be made of material intended for motorsorts use with a minimum thickness of one-half (1/2). Padding conforming to SFI spec 45.1 is recommended.
  3. Evergreen Drift reserves the right to not approve a roll cage based on safety concerns. Cages should be built to Formula Drift specs first but SCCA, NASA, FIA, and other wheel to wheel road racing approved cages are acceptable. It is the drivers responsibility to provide the rules proving conformity to any standard other than Formula Drift.
  4. A minimum 4 point roll bar with a single door bars that extend from the main hoop and terminates at the base of the A pillar on both the driver and passenger side is required. Four point cages with a single door bar must retain the factory doors with unmodified side impact protection for both the driver and passenger side. 6 point cages with door bars meeting Formula Drift ProAm rules specification may modify the factory side impact door beams and use aftermarket doors.
  5. 4 Point cages are recommended for vehicles that are still street driven. Formula Drift spec 6 point cages offer additional protection for track only cars that will always be used with a helmet.
